Product Description

The MBRP S7211304 Pro Series Race Profile Axle-Back Exhaust System is engineered for the 2018-2023 Ford Mustang GT with the 5.0L V8, transforming the rear exhaust into a high-flow powerhouse that unleashes the Coyote engine's full potential with an aggressive, race-inspired roar. Mandrel-bent 2.5-inch T304 stainless steel tubing replaces the factory mufflers with a straight-through design, reducing backpressure to deliver dyno-verified horsepower and torque gains while producing a deep, throaty rumble that echoes through the cabin without intrusive drone--perfect for track days, canyon carving, or daily cruises in RWD coupes or convertibles. This lightweight system sheds pounds over OEM components, improving balance and throttle sharpness without compromising emissions compliance.

Installation involves a simple cut-and-clamp process on the factory tailpipes, completing in 1-2 hours with basic tools and no welding required, utilizing OEM hangers for precise alignment and vibration-free operation. The premium T304 construction with dual-wall polished quad tips withstands heat, salt, and abuse for long-term durability, backed by a lifetime warranty. It fits all GT trims without active exhaust but excludes those variants or later S650 Mustangs (2024+) due to routing changes. With MBRP's motorsport heritage, the S7211304 elevates your Mustang's performance and presence, turning every rev into a statement of power and precision.
